Abstract
Description
本発明は、静脈注射や採血等の処置を患者に施すに際し、血管の位置を特定して容易に穿刺することができる穿刺用照明装置に関する。 The present invention relates to an illumination device for puncture that can be easily punctured by specifying the position of a blood vessel when performing treatment such as intravenous injection or blood collection on a patient.
従来、医療現場にあっては、患者に対して静脈注射や採血等の処置を施すに際し、穿刺する部位よりも体幹よりに駆血帯を巻きつけて静脈血を鬱滞させることにより、皮膚の表面に血管（静脈）を浮き上がらせて、これによって患者の血管の位置を把握している。 Conventionally, in the medical field, when performing treatment such as intravenous injection or blood sampling on a patient, a tourniquet is wrapped around the trunk rather than the puncture site to stagnate the venous blood. A blood vessel (vein) is raised on the surface, thereby grasping the position of the patient's blood vessel.
また、特許文献１には、静脈と他の組織との吸光特性の違いによる反射光の光量の相違から静脈の位置を確認することができる静脈探査装置が提案されており、特許文献２には、患者の腕部の両側面及び背面より光を透過させることによって、肘の内側で血管の陰影を診られるようにベルト式採血用透光照明器が提案されている。 Further, Patent Document 1 proposes a vein exploration device that can confirm the position of a vein from the difference in the amount of reflected light due to the difference in light absorption characteristics between the vein and other tissues. A belt-type translucent illuminator for blood collection has been proposed so that the shadow of a blood vessel can be examined inside the elbow by transmitting light from both sides and the back of the patient's arm.
しかしながら、特許文献１では、赤色ないし赤外線領域の７００〜２０００ｎｍの波長光を照射して、静脈と他の組織からの反射光の光量の差によって二つのカーソルの位置を合わせることで静脈を探査しているが、静脈の位置を目視によって特定するまでには至っていない。位置合わせがなされた二つのカーソルを結ぶ線の下に、静脈があると推測しているに過ぎない。 However, in Patent Document 1, the vein is probed by irradiating light with a wavelength of 700 to 2000 nm in the red or infrared region and aligning the two cursors according to the difference in the amount of reflected light from the vein and other tissues. However, the position of the vein has not been identified by visual inspection. It is only guessing that there is a vein under the line connecting the two aligned cursors.
また、特許文献２では、患者の腕等にベルトを巻き付ける手間を要するだけでなく、発光ユニットが患者の肌に密着した際の火傷を避けるための冷却機構が必要である。 Moreover, in patent document 2, not only the time which winds a belt around a patient's arm etc. is required, but the cooling mechanism for avoiding the burn when a light emission unit closely_contact | adheres to a patient's skin is required.
本発明は、上記の事情に鑑みてなされたものであり、ベルトを巻き付ける等の煩わしい手間を要することなく、穿刺する部位に照明光を照射するだけで、穿刺する静脈の位置を目視によって容易に特定することができる穿刺用照明装置の提供を目的とする。 The present invention has been made in view of the above circumstances, and it is easy to visually check the position of a puncture vein by simply irradiating the puncture site with illumination light without requiring troublesome work such as winding a belt. An object is to provide a lighting device for puncture that can be specified.
本発明に係る穿刺用照明装置は、穿刺する際に静脈の位置を目視によって特定するための穿刺用照明装置であって、４００〜５００ｎｍの青色波長領域の第一照明光と、６００〜６６０ｎｍの赤色波長領域の第二照明光とを照射する光源を備える構成としてある。 The illuminating device for puncturing according to the present invention is a illuminating device for puncturing for visually identifying the position of a vein when puncturing, and includes first illumination light in a blue wavelength region of 400 to 500 nm, and 600 to 660 nm. The light source that emits the second illumination light in the red wavelength region is provided.
本発明によれば、穿刺する部位に特定の波長領域の照明光を照射するだけで、静脈の位置を目視によって容易に特定することができる。 According to the present invention, the position of the vein can be easily identified visually by simply irradiating the puncture site with illumination light of a specific wavelength region.
以下、本発明に係る穿刺用照明装置の実施形態について説明する。 Hereinafter, embodiments of the puncture illumination device according to the present invention will be described.
本実施形態の穿刺用照明装置は、静脈注射や採血等の処置を患者に施すに際し、穿刺する静脈の位置を目視によって特定するためのものである。そして、青色波長領域の第一照明光と、赤色波長領域の第二照明光とを照射する光源を備えており、これら特定の波長領域の照明光を、患者の腕等の穿刺する部位に照射するように構成されている。 The illuminating device for puncture of this embodiment is for visually identifying the position of a vein to be punctured when a patient is subjected to treatment such as intravenous injection or blood sampling. A light source for irradiating the first illumination light in the blue wavelength region and the second illumination light in the red wavelength region is provided, and the illumination light in the specific wavelength region is irradiated to the puncture site such as the patient's arm. Is configured to do.
血液中の赤血球に含まれるヘモグロビンが酸素と結合した酸化ヘモグロビンは、赤色波長領域の光をほとんど吸収しない。このため、酸化ヘモグロビンを多く含む動脈血は赤く見えるに対して、酸素が遊離した還元ヘモグロビンを多く含む静脈血は青黒く見える。これは、還元ヘモグロビンにあっては、酸化ヘモグロビンと比べて青色波長領域の光の吸収量が大きく減少するためであり、本実施形態では、このような還元ヘモグロビンの吸光特性を利用して、目視による静脈の位置の特定を可能としている。 Oxyhemoglobin in which hemoglobin contained in red blood cells in blood is combined with oxygen hardly absorbs light in the red wavelength region. For this reason, arterial blood containing a large amount of oxygenated hemoglobin appears red, whereas venous blood containing a large amount of reduced hemoglobin from which oxygen is released appears blue. This is because, in reduced hemoglobin, the amount of light absorbed in the blue wavelength region is greatly reduced compared to oxidized hemoglobin. In the present embodiment, the light absorption characteristics of such reduced hemoglobin are used to make visual observations. It is possible to specify the position of the vein.
すなわち、静脈血に多く含まれる還元ヘモグロビンは、前述した吸光特性から、穿刺用照明装置が備える面光源から照射された青色波長領域の第一照明光と、赤色波長領域の第二照明光を吸収し難い。このため、穿刺する部位に照射された青色波長領域の第一照明光と、赤色波長領域の第二照明光は、その一部が静脈血に多く含まれる還元ヘモグロビンによって反射され、その反射光により患者の皮膚表面に静脈が透けて見えるようになる。これによって、穿刺する静脈の位置を目視によって特定することができる。 That is, reduced hemoglobin, which is abundant in venous blood, absorbs the first illumination light in the blue wavelength region and the second illumination light in the red wavelength region emitted from the surface light source provided in the puncture illumination device, from the light absorption characteristics described above. It is hard to do. For this reason, the first illumination light in the blue wavelength region and the second illumination light in the red wavelength region irradiated to the part to be punctured are reflected by the reduced hemoglobin that is partly contained in venous blood, and the reflected light The veins can be seen through the patient's skin surface. As a result, the position of the vein to be punctured can be identified visually.
このような原理に基づいて、穿刺する静脈の位置を目視によって特定するにあたり、青色波長領域の第一照明光ＦＬは、還元ヘモグロビンに吸収され難い４００〜５００ｎｍの波長範囲とし、赤色波長領域の第二照明光ＳＬは、還元ヘモグロビンに吸収され難い６００〜６６０ｎｍの波長範囲とする。そして、穿刺用照明装置が備える光源から照射された照明光の多くが、還元ヘモグロビンによって反射されるようにするためには、第一照明光ＦＬが、４００〜５００ｎｍの青色波長領域において、波長４４０〜４６０ｎｍに最大ピークを示し、かつ、半値全幅ＷＨ１が１００ｎｍ以下、好ましくは７０ｎｍ以下のスペクトル成分を含み、第二照明光ＳＬが、６００〜６６０ｎｍの赤色波長領域において、波長６２０〜６４０ｎｍに最大ピークを示し、かつ、半値全幅ＷＨ２が６０ｎｍ以下、好ましくは２５ｎｍ以下のスペクトル成分を含んでいるのが好ましい（図１参照）。 Based on such a principle, when the position of the vein to be punctured is specified by visual observation, the first illumination light FL in the blue wavelength region is set to a wavelength range of 400 to 500 nm that is hardly absorbed by reduced hemoglobin, and the first wavelength in the red wavelength region. The second illumination light SL has a wavelength range of 600 to 660 nm which is difficult to be absorbed by reduced hemoglobin. And in order to make most of the illumination light irradiated from the light source with which the illuminating device for puncture is reflected by the reduced hemoglobin, the first illumination light FL has a wavelength 440 in a blue wavelength region of 400 to 500 nm. The maximum peak at ˜460 nm and the full width at half maximum WH1 includes a spectral component of 100 nm or less, preferably 70 nm or less, and the second illumination light SL has a maximum peak at a wavelength of 620 to 640 nm in a red wavelength region of 600 to 660 nm. In addition, it is preferable that the full width at half maximum WH2 includes a spectral component of 60 nm or less, preferably 25 nm or less (see FIG. 1).
図１は、本実施形態において、穿刺用照明装置が備える光源から照射される照明光の理想的なスペクトル分布の一例である。当該照明光のスペクトル分布は、第一照明光ＦＬと第二照明光ＳＬのそれぞれが、少なくとも上記スペクトル成分を含んでいればよい。上記スペクトル成分が含まれていれば、その多くが還元ヘモグロビンによって反射され、静脈の特定がより容易になるが、第一照明光ＦＬと第二照明光ＳＬには、静脈の特定を妨げない範囲で、上記スペクトル成分以外の成分が含まれていてもよい。
また、穿刺用照明装置が備える光源から照射される照明光には、静脈の特定を妨げない範囲で、４００〜５００ｎｍの波長範囲（第一照明光）と６００〜６６０ｎｍの波長範囲（第二照明光）以外の波長の光が含まれていてもよい。
FIG. 1 is an example of an ideal spectral distribution of illumination light emitted from a light source included in the puncture illumination device in the present embodiment. The spectral distribution of the illumination light may be such that each of the first illumination light FL and the second illumination light SL includes at least the spectrum component. If the above spectral components are included, most of them are reflected by reduced hemoglobin, and the veins can be identified more easily. However, the first illumination light FL and the second illumination light SL do not interfere with the vein identification. In addition, components other than the above spectral components may be included.
In addition, the illumination light emitted from the light source included in the puncture illumination device has a wavelength range of 400 to 500 nm (first illumination light) and a wavelength range of 600 to 660 nm (second illumination) within a range that does not interfere with the specification of the vein. Light having a wavelength other than (light) may be included.
また、本実施形態の穿刺用照明装置からの照明光によって、より鮮明に患者の皮膚表面に静脈が見えるようにするには、赤色波長領域の第二照明光ＳＬの光量に比べ、青色波長領域の第一照明光ＦＬの光量が大きくなるように調整するのが好ましい。より具体的には、青色波長領域の第一照明光ＦＬの光量と、赤色波長領域の第二照明光ＳＬの光量比が、１０：８〜１０：６であるのが好ましい。
なお、光量は、それぞれの波長領域における発光強度［ａ．ｕ．（任意単位）］の積分値から求めるものとする。
Further, in order to make the veins more clearly visible on the patient's skin surface by the illumination light from the puncture illumination device of the present embodiment, the blue wavelength region is larger than the light amount of the second illumination light SL in the red wavelength region. It is preferable to adjust so that the amount of the first illumination light FL increases. More specifically, the light amount ratio of the first illumination light FL in the blue wavelength region and the second illumination light SL in the red wavelength region is preferably 10: 8 to 10: 6.
Note that the amount of light depends on the emission intensity [a. u. (Arbitrary unit)].
また、還元ヘモグロビンは緑色波長領域の光を吸収する吸光特性を示すため、緑色波長領域の光は、静脈の位置の特定に何ら寄与しない。そればかりか、静脈によって反射された青色波長領域の第一照明光ＦＬと赤色波長領域の第二照明光ＳＬに、緑色波長領域の光が加わると白色になってしまい、静脈の特定を妨げてしまうおそれがある。
このような理由から、本実施形態の穿刺用照明装置が備える光源から出射される照明光には、緑色波長領域の光が可能な限り含まれないようにするのが好ましい。より具体的には、面光源から出射される照明光中の５４０〜５８０ｎｍの緑色波長領域の光量が、第一照明光ＦＬの光量の５％以下とするのが好ましい。当該緑色波長領域の光は、カットフィルター等の光学フィルターにより実質的にゼロにすることがより好ましい。
In addition, since reduced hemoglobin exhibits a light absorption characteristic that absorbs light in the green wavelength region, the light in the green wavelength region does not contribute to the specification of the position of the vein. In addition, when light in the green wavelength region is added to the first illumination light FL in the blue wavelength region and the second illumination light SL in the red wavelength region reflected by the veins, the light turns white, which prevents the vein from being identified. There is a risk that.
For this reason, it is preferable that the illumination light emitted from the light source provided in the puncture illumination device of the present embodiment does not include light in the green wavelength region as much as possible. More specifically, the light amount in the green wavelength region of 540 to 580 nm in the illumination light emitted from the surface light source is preferably 5% or less of the light amount of the first illumination light FL. More preferably, the light in the green wavelength region is made substantially zero by an optical filter such as a cut filter.
また、目視による静脈の位置の特定を可能とするには、穿刺する部位に照明光を照射したときに、静脈とそれ以外の部位からの反射光とを明確に区別できるように、皮膚表面に均一に照明光が照射され、皮膚下からの反射光も均一となるようにすることが望まれる。本実施形態の穿刺用照明装置が備える光源の具体的な構成は特に限定されるものではないが、上記の理由から、本実施形態の穿刺用照明装置が備える光源は、青色波長領域の第一照明光ＦＬと、赤色波長領域の第二照明光ＳＬとを面状に照射する面光源であるのが好ましい。 In addition, in order to be able to identify the position of the vein by visual inspection, when the puncture site is irradiated with illumination light, the vein surface and the reflected light from other sites can be clearly distinguished from each other on the skin surface. It is desired that the illumination light is uniformly irradiated and the reflected light from under the skin is also uniform. The specific configuration of the light source included in the puncture illumination device of the present embodiment is not particularly limited, but for the above reason, the light source included in the puncture illumination device of the present embodiment is the first in the blue wavelength region. A surface light source that irradiates the illumination light FL and the second illumination light SL in the red wavelength region in a planar shape is preferable.
本実施形態の穿刺用照明装置が備える光源としては、例えば、白熱電球、放電灯、レーザー、発光ダイオード等を一次光源として、バンドパスフィルター、カットフィルター等の特定波長の光のみを透過する光学フィルターにより、特定の波長領域の照明光を照射するようにしたものを用いることができる。光源が面光源である場合には、拡散板、導光板等によって照明光を面状に照射するように構成したものであってもよい。
特定の波長領域の照明光を必要とする本実施形態では、発光材料を調製することで放出される光の波長を制御することができる発光ダイオード（ＬＥＤ）を用いるのが好ましい。発光ダイオードのなかでも、単独で用いても面発光によるムラのない拡散光が得られ、光の広がり具合を示す配光性にも優れていることから、有機エレクトロルミネッセンス（有機ＥＬ）が特に好ましい。有機ＥＬは、面発光で眩しさのない自然な柔らかい光を発することに加え、理想的な球形配向により、穿刺する施術者の手暗がりが発生し難いという利点もある。
As a light source provided in the puncture illumination device of the present embodiment, for example, an incandescent bulb, a discharge lamp, a laser, a light emitting diode or the like is used as a primary light source, and an optical filter that transmits only light of a specific wavelength, such as a band pass filter or a cut filter. Thus, it is possible to use an illumination light of a specific wavelength region. When the light source is a surface light source, it may be configured to irradiate illumination light in a planar shape with a diffusion plate, a light guide plate, or the like.
In this embodiment that requires illumination light in a specific wavelength region, it is preferable to use a light emitting diode (LED) that can control the wavelength of light emitted by preparing a light emitting material. Among the light emitting diodes, organic electroluminescence (organic EL) is particularly preferable because even when used alone, diffused light without unevenness due to surface light emission is obtained and light distribution indicating the extent of light spreading is excellent. . In addition to emitting natural soft light without glare due to surface emission, the organic EL has an advantage that it is difficult for the practitioner to darken the hand due to the ideal spherical orientation.
以上のように、本実施形態の穿刺用照明装置によれば、穿刺する部位に照明光を照射するだけで、静脈の位置を目視によって特定することができ、特許文献２のように、患者の腕等にベルトを巻き付ける等の煩雑な手間を要することない。このため、静脈注射や採血等の処置を施す患者が、乳幼児、特に、出生後に保育器に入らなければならないような健全な発育をしていない乳児であっても、静脈の位置を短時間で容易に特定することができ、誤った穿刺による事故を未然に防ぐことも期待できる。 As described above, according to the puncture illumination device of the present embodiment, the position of the vein can be identified by visual observation only by irradiating the puncture site with illumination light. There is no need for troublesome work such as wrapping a belt around an arm or the like. For this reason, even if the patient undergoing treatment such as intravenous injection or blood sampling is an infant, especially an infant who does not have a healthy growth that must enter an incubator after birth, the position of the vein should be reduced in a short time. It can be easily identified and can be expected to prevent accidents caused by erroneous puncture.
次に、本実施形態の穿刺用照明装置の具体な実施例について、図面を参照しつつ説明する。 Next, specific examples of the puncture illumination device of the present embodiment will be described with reference to the drawings.
